在某些情况下,通常在从初始搜索缓存值之后,我无法让 mdb_autocomplete 下拉菜单单击一下就关闭。我经常需要双击我的选择才能关闭它。我通过 Ajax 调用服务方法和控制器操作方法动态填充下拉列表中的值,该方法在活动目录中搜索前 30 个名称值。在用户在 mdb_autocomplete 选择框中输入至少 3 个值之前,不会发生回调。下拉列表的回调和填充效果很好,但是选择值之后的点击事件通常不会关闭下拉列表。此外,我们被迫在正常引导库上使用 mdb boostrap。我已经包括了视图,服务,

看法:

        <div class="form-group">
            <label class="font-weight-bold" for="RequestorSearchInput">Requestor</label>
            <input type="text" id="RequestorSearchInput" name="RequestorSearchInput" class="form-control mdb-autocomplete" />
            <span id="loading_data_icon"></span>
        </div> 

服务方式:

    public List<string> GetRequestor(string aRequestor)
    {
        IEnumerable<Dictionary<string, string>> requestorNames;
        using (ActiveDirectoryService service = new ActiveDirectoryService(<LDAP Domain Name>))
        {
            string[] propertiesToLoad = new string[] { "displayName" };
            //requestorNames = service.SearchByPartialUsername(aRequestor, propertiesToLoad).Take(30).Union(service.SearchBySurname(aRequestor, propertiesToLoad).Take(30));
            requestorNames = service.SearchBySurname(aRequestor, propertiesToLoad).Take(30);
        }
        return requestorNames.SelectMany(x => x.Values).Where(y => y.IndexOf(",", StringComparison.Ordinal) >= 0).Distinct().ToList();
    }

打字稿:

private handleRequestorSearch() {
    let options: string[] = new Array();

    // @ts-ignore
    let searchval = $("#RequestorSearchInput").val().length;

    if (searchval >= 3) {
        $.ajax({
            url: main.getControllerHREF("GetRequestor", "Search"),
            method: "POST",
            data: {
                requestor: $("#RequestorSearchInput").val()
            },
            async: false,
            dataType: "json",
            success: function (names) {

                $.each(names, function () {
                    options.push(this);
                });

                // @ts-ignore
                $("#RequestorSearchInput").mdb_autocomplete({
                    data: options
                }).select(function () {
                    $("#RequestorSearchInput").focus;
                });

            }
        });
    }
}
